OP didn't ask for 10 cents, they asked what they could do to their "318" to go "under 14's". Sounded like a very reasonable, achievable request to me....
well, there you go, another opportunity for you to share your 318 knowledge with OP. 318canrun.
I like the idea to build what you have. If I'm starting fresh, at a minimum I'm going 470, ninety more cubes than a 360. even the 408 is a little small.
